Wind hybrid power

A wind-hydro system generates electric energy combining wind turbines and pumped storage.
The combination has been the subject of long-term discussion, but had
not been implemented at a single location as of late 2010.

Wind-hydro stations dedicate all, or a significant portion, of their
wind power resources to pumping water into pumped storage reservoirs.
These reservoirs are an implementation of grid energy storage.

Advantages

Wind and its generation potential is inherently variable. However,
when this energy source is used to pump water into reservoirs at an
elevation (the principle behind pumped storage), the potential energy of
the water is relatively stable and can be used to generate electrical
power by releasing it into a hydropower plant when needed. The combination has been described as particularly suited to islands that are not connected to larger grids.
